Definitions

  • the present invention is generally directed to actuator rods used in push-pull mechanisms and, more specifically, to a multi-piece, multi-material actuator rod.
  • rod members are used to translate movement of one mechanical part to another associated mechanical part, such as in push-pull mechanisms.
  • these rod members are of one-piece construction and require special machining of their end sections for connection of the rod members to other devices. Such machining necessitates additional time and fabrication effort, as well as loss of material which results in increased costs. This is of particular disadvantage since substantial heavy materials must be utilized to form the rod members in order that they may withstand imposed stress, strain and torque loading, particularly when utilized in a push-pull function.
  • the present invention avoids the shortcomings and disadvantages of known rod members by providing for a two-piece actuator rod, with one piece comprised of a rod member that is preferably made of steel plate having stock thickness and formed by punching, thereby resulting in more economical production of same.
  • the second piece of this actuator rod includes a jacket member which is slid onto the rod member for reinforcing same.
  • the jacket member is made of any rigid material, preferably of plastic and particularly including some type of crystalline thermoplastic polymer.
  • the jacket member may be bonded directly to the rod member.
  • the jacket and rod members are mechanically locked together by mounting means which connects both members to an associated device.
  • An object of the invention is to provide an actuator rod comprising a rod member with a first hole passing therethrough at a first end and a second hole passing therethrough at a second end thereof, and a jacket member having an axially extending slot therethrough for registration therein of the first end of the rod member.
  • the jacket member further includes an opening passing therethrough, with the opening being located in the jacket member such that when the first end of the rod member is registered within the slot, the first hole is aligned with the opening.
  • the rod member is in the form of a flat steel bar and the jacket member is formed from a crystalline thermoplastic polymer.
  • the actuator rod includes a stopping means for preventing the rod member from passing completely through the jacket member.
  • This stopping means preferably includes at least one laterally extending ear at the first end of the rod member, the ear including a forward facing shoulder that abuts a complementing rearward facing shoulder on the jacket member.
  • the jacket member is preferably cylindrical in configuration with a conically tapered end extending towards the second end of the rod member and a flat opposite end. The jacket member includes a circumferential groove located between its flat and tapered ends.
  • FIG. 1 is a side elevational view of an actuator rod according to a preferred embodiment of the present invention
  • FIG. 2 is an end view of the actuator rod of FIG. 1 when viewed from the left side thereof;
  • FIG. 3 is an end view of the actuator rod of FIG. 1 when viewed from the right side thereof;
  • FIG. 4 is a plan view of a rod member forming one piece of the actuator rod of FIG. 1;
  • FIG. 5 is an end view of the rod member of FIG. 4 when viewed from the left side thereof;
  • FIG. 6 is an end view of the rod member of FIG. 4 when viewed from the right side thereof;
  • FIG. 7 is a side elevational view of a jacket member forming the other piece of the actuator rod of the invention.
  • FIG. 8 is a sectional view taken along the line 8--8 of FIG. 7.
  • rod 1 is composed of two component pieces, including a rod member 2 and a jacket member 4.
  • a headed end 12 of rod member 2 is provided with a hole 14 therethrough for inserting a pin 15 or other similar device for connecting actuator rod 1 to a clevis or other associated device.
  • An end 16 of rod member 2 includes a mounting means in the form of a hole 18 which allows for the connection of the other end of actuator rod 2 to another associated device by means of a pin.
  • Rod member 2 is preferably formed by punching a steel plate of stock thickness. Rod member 2 can also be treated to prevent or retard corrosion of its surfaces which may be exposed to high humidity or critical environments.
  • jacket member 4 is generally of a cylindrical configuration.
  • Jacket member 4 can be formed from a variety of materials, preferably plastic material and specifically from those plastics including crystalline thermoplastic polymers offering high mechanical strength, stiffness and toughness.
  • a first end 22 of jacket member 2 includes a hole 24 which, when actuator rod 1 is assembled, is aligned with hole 14 of rod member 2.
  • Jacket member 4 further includes a slot 26 which passes completely through jacket member 4 along its longitudinal axis and disposed perpendicular to the axis of hole 24. The width and thickness of slot 26 is such that rod member 2 may be slid into slot 26.
  • jacket member 4 thereby prevents rod member 2 from passing completely through jacket member 4.
  • Jacket member 4 further includes a circumferential groove 6 for receiving a mounting ring or other similar appliance carried by an associated device.
  • Jacket member 4 provides transverse strength to rod member 2, particularly in the push mode of a push-pull mechanism, or when rod member 2 is subjected to bending or torque stresses.
